so check if the environment variable QMAKESPEC is set to win32-msvc2005 (to list the variables just type "set", to set use: set QMAKESPEC=win32-msvc2005)
That fixes the problem! When I saw g++/msvc/......./msvc2005 from the output of qconfigure.bat my eyes never passed the second option so used qconfigure.bat msvc Bo
